Engineering Selection Recommendations

All three parts—ATSAML11E15A-MFTKPH, ATSAML11E15A-MFT, and ATSAML10E15A-MFT—are Active products manufactured by Microchip Technology and are ROHS3 compliant. Selection between these parts is determined by packaging format requirements and inventory availability rather than electrical or functional differences.

ATSAML11E15A-MFTKPH is specified for applications requiring Tape & Reel packaging in the SAM L11 series variant.

ATSAML11E15A-MFT provides identical electrical and mechanical specifications with Tape & Reel packaging, differing only in the packaging suffix designation within the SAM L11 series.

ATSAML10E15A-MFT is functionally equivalent across all critical parameters and is available in Cut Tape & Digi-Reel format. This part represents the SAM L10 series variant with identical core specifications.

All three parts meet the same compliance requirements (ROHS3, REACH Unaffected, MSL 3) and operate within the same temperature range (-40°C ~ 125°C). Selection should be based on packaging format availability, supply chain requirements, and design documentation specifications.

Frequently Asked Questions (FAQ)

Q: Can ATSAML10E15A-MFT be used as a direct replacement for ATSAML11E15A-MFTKPH?

A: Yes. Both parts share identical core processor architecture (ARM Cortex-M23), memory configuration (32KB FLASH, 8KB RAM, 2KB EEPROM), operating speed (32MHz), I/O count (25), connectivity options (I2C, LINbus, SPI, UART/USART), and package dimensions (32-VQFN 5x5). The primary difference is the series designation (SAM L10 vs. SAM L11) and packaging format (Cut Tape & Digi-Reel vs. Tape & Reel).

Q: What is the difference between ATSAML11E15A-MFTKPH and ATSAML11E15A-MFT?

A: These parts are electrically and mechanically identical. The difference lies in the packaging format suffix: MFTKPH indicates Tape & Reel packaging, while MFT also indicates Tape & Reel. Both are SAM L11 series devices with identical specifications.

Q: Are there any electrical performance differences between SAM L10 and SAM L11 series?

A: No. The ATSAML10E15A-MFT and ATSAML11E15A-MFTKPH share identical electrical specifications including processor speed, memory size, voltage supply range, data converter configuration, and peripheral set.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the PCB footprint accommodates the 32-VQFN (5x5) package with exposed pad. All three parts use identical pin configurations and package dimensions.

Q: What packaging formats are available for these substitutes?

A: ATSAML11E15A-MFTKPH and ATSAML11E15A-MFT are supplied in Tape & Reel (TR) format. ATSAML10E15A-MFT is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly process requirements and volume specifications.

Q: Are all three parts ROHS3 compliant?

A: Yes. ATSAML11E15A-MFTKPH, ATSAML11E15A-MFT, and ATSAML10E15A-MFT are all ROHS3 compliant with MSL rating 3 (168 Hours).
